Taylor Swift's Real & Rumored Romances

Their romance was first reported by The X Factor host Mario Lopez, who said he spotted the young couple canoodling backstage of the FOX singing competition after she had performed onstage.

Swift and Styles were then spotted jet-setting around the globe -- including touching base at the British heartthrobs hometown in the U.K. and sharing a New Year's Eve kiss in New York City -- before breaking things off in early January 2013.
